“…The formation of UPy dimers leads to the effective cross‐linking and improved mechanical strength of the resultant polymers, whereas, upon stretching, the continuous unfolding and disassociation of UPy dimers enables the final polymers to exhibit high extensibility and toughness. Therefore, to date, many H‐bond cross‐linked polymers with tunable mechanical properties have been designed by chemically attaching UPy units to main chains, side chains, or chain ends …”

“…UPy units can also be chemically attached at the side chain of the resultant polymers . For example, Long and co‐workers reported the synthesis of thermoreversible poly(alkyl acrylates) via free‐radical copolymerization of UPy‐containing methacrylate monomer (SCMHB MA) and butyl acrylate.…”

“…Besides thermoplastic elastomers, UPy units have also been introduced into thermoplastic polyolefins to improve mechanical properties and interfacial compatibility of immiscible polyolefin blends . However, UPy units do not perform in plastics as well as in elastomers, because the crystallization of the former significantly restricts the mobility of chain segments and the association and disassociation of UPy units.…”

“…For example, Coates and co‐workers demonstrated the synthesis of wax‐like 1‐hexene copolymers with various amounts of UPy functionalized alkene, and the resultant polymers showed superior tensile strength over the the homopolymer counterpart because of the cross‐links of UPy. Moreover, Bosman and co‐workers recently prepared supramolecular polypropylene (PP) with side UPy groups, and the extensibility of the resultant PP exhibited a strong testing‐temperature dependence, especially at temperatures above 100 °C, at which UPy units can move freely to form dimers and give rise to effective cross‐linking.…”

to traditional metallic and ceramic materials. [1] Therefore, it has been desirable to create high-performance polymeric materials that are mechanically robust, thermostable, and even healable for meeting practical applications in industry. The creation of cross-linked polymers has been regarded as one promising approach for creating strong and thermally stable polymers. [3][4][5] Cross-linked polymers normally exhibit superior mechanical and thermostable performances to their uncrosslinked counterparts. [6][7][8][9][10] Traditionally, a chemically covalent approach has been the primary means for realizing the cross-linking of polymeric materials. As compared with the parent polymer, cross-linked polymers normally gain enhanced mechanical strength and thermal stability. [6][7][8][9][10][11] This strategy, however, gives rise to significantly reduced extensibility because of the exclusive molecular mechanism between strength, extensibility, and toughness. [12][13][14][15] By contrast, noncovalent cross-linking can lead to increased mechanical strength without sacrificing the extensibility and toughness of polymeric materials. Such cross-linking can be realized by adopting strong noncovalent interactions including Coulombic interactions, [11] dipoledipole interactions, [12] metal coordination, [13] and hydrogenbonding (H-bonding) interactions. [5,16] To date, H-bonding is among the most extensively employed noncovalent interactions for the creation of cross-linked polymeric materials with tunable microstructure and tailor-made performances because of its directionality, versatility, and reversibility. In 1997, Meijer and co-workers [17] pioneered the synthesis of the first reversible cross-linked polymer by reacting a trifunctional copolymer of hydroxyl-terminated poly(propylene oxide) with diisocyanate and then 2-ureido-4-pyrimidone (UPy) units capable of forming quadruple H-bonds. The final poly mer shows a relatively high plateau modulus because such H-bond cross-links can serve as entanglements in a linear polymer. Following the synthesis of some uncross-linked polymeric materials containing UPy motifs, [17][18][19] Meijer's group has further synthesized many cross-linked polymeric materials based on UPy motifs. [20][21][22] On the other hand, in many natural biological materials, such as silk [23][24][25][26] and muscle, [27] multiple H-bonding interactions have recently been revealed to play a critical part in realizing a unique combination of high strength, great It has always been critical to develop high-performance polymeric materials with exceptional mechanical strength and toughness, thermal stability, and even healable properties for meeting performance requirements in industry. Conventional chemical cross-linking leads to enhanced mechanical strength and thermostability at the expense of extensibility due to mutually exclusive mechanisms. Such major challenges have recently been addressed by using noncovalent cross-linking of reversible multiple hydrogen-bonds (H-bonds) that widely exist in biological...

“…The lower decrease amplitude of recovery rate revealed that the copolymer P(AM-DAC-AMTU) had better adsorption stability and longer acting time. For supramolecular systems, the high hot rolling temperature destroyed the hydrogen bonding between the copolymers and the guanidinium salts and increases the water solubility of the guanidinium salts, which caused the reduce of compound effect and the loss of larger amounts of guanidinium salts molecular, resulting in an obvious decrease in the cuttings recovery rate [46].…”

Herein, novel hyperbranched polyamidoamine guanidinium salts (GS-h-PAMAM) and two cationic acrylamide copolymers P(AM-DAC-ABSM) and P(AM-DAC-AMTU) were successfully prepared. Then, self-assembly supramolecular systems were synthesized by directly mixing GS-h-PAMAM with copolymers in aqueous solution, and the mechanism of the self-assembly process was speculated. FT-IR, NMR, and SEM were used for structural confirmation. Furthermore, the excellent solution properties revealed that the supramolecular systems had potential application in clay hydration inhibitors. More importantly, utilizing functionalized hyperbranched polyamidoamine in the synthesis self-assembly supramolecular systems was an effective strategy for expanding their application fields and developing new functional materials, providing a powerful reference for the next study.

The development of multifunctional bio‐based materials with closed‐loop chemically recyclable plastics can be a paramount response to the worldwide plastic waste predicament. However, the trade‐off dilemma between the high performance and easy recycling performance of these materials still encounters huge challenges. In this contribution, inspired by the significant contribution of the hydrogen bonding networks to enhanced mechanical and gas barrier performance as well as the cosolvents to enhance recycling performance, a novel polyester material (PBHyF) synthesized by bio‐based monomers that integrate high‐performance and efficient chemical closed‐loop is presented. PBHyF show ultra‐high mechanical properties (83.2 MPa, 233.9%) and barrier properties (CO2 0.0157 barrer, O2 0.0071 barrer, H2O 5.518E‐15 g·cm/cm2·s·Pa) that are greater than bio‐based materials and most engineering plastics of previous work. More significantly, PBHyF also exhibits multifunctionality with excellent ultraviolet shielding properties, solvent‐resistant properties, and easy recycling performance. The initial monomers of PBHyF can be obtained in exceptional yields (>90.0%) and purity (>99.0%) under mild conditions by a simple energy‐efficient rapid chemical‐solvolysis strategy, even with polyolefin blend plastics. Further possesses similar high‐performance repolymerized polyester comparable to the polyester before recycling. Hence, these state‐of‐art high‐performance and easy‐recycling bio‐based materials provide a new approach for a green, sustainable material economy.
